NCP5351 4 A Synchronous Buck Power MOSFET Driver The NCP5351 is a dual MOSFET gate driver optimized to drive the gates of both high side and low side Power MOSFETs in a Synchronous Buck converter. The NCP5351 is an excellent companion to multiphase controllers that do not have integrated gate drivers, such as ON Semiconductor’s CS5323, CS5305 or CS5307. This architecture provides a power supply designer the flexibility to locate the gate drivers close to the MOSFETs. The 4.0 A d.
